[0002] With the rapid development of the mobile communications industry, communication equipment and base stations, as key components, are poised for explosive growth. Communication equipment is generally a high-precision instrument with extremely demanding operating environment requirements, necessitating air conditioning to maintain constant temperature and humidity. Furthermore, to ensure the normal operation of electronic communication equipment, air conditioning in communication base stations often needs to run 24 hours a day, resulting in enormous energy consumption. Statistics show that in my country's communications industry, base station air conditioning accounts for approximately 20% to 40% of the total energy consumption of communication base stations, amounting to as much as 7 billion kWh annually. Therefore, air conditioning equipment in communication base stations urgently needs a green and low-carbon transformation to achieve energy-saving and emission-reducing operation.

[0003] Traditional air conditioning energy-saving control methods calculate the difference between the real-time detected ambient temperature and the set temperature, and then automatically switch the indoor fan on and off based on the difference, resulting in low energy efficiency. Summary of the Invention

[0013] The rate of temperature change of the target equipment is obtained by analyzing the real-time temperature of the target equipment after the air conditioner is turned on.

[0014] The operating parameters of the air conditioner are adjusted according to the control method corresponding to the temperature range to which the target equipment temperature belongs and the rate range to which the target equipment temperature change rate belongs.

[0015] In one embodiment, the step of adjusting the operating parameters of the air conditioner according to the adjustment method corresponding to the temperature range to which the target device temperature belongs and the rate range to which the rate of change of the target device temperature belongs includes:

[0031] When the processor temperature is lower than the second preset temperature, the step of acquiring the second temperature data related to the target device in real time is executed;

[0032] When the processor temperature is greater than or equal to the second preset temperature, the compressor operating frequency of the air conditioner is reduced and the outdoor fan speed of the air conditioner is reduced until the processor temperature is less than the third preset temperature and the duration is greater than the preset duration.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0059] As described in the background section, in scenarios requiring strict and precise control of temperature and relative humidity, such as communication base stations and computer rooms, energy-intensive air conditioning equipment urgently needs a green and low-carbon transformation to achieve energy-saving and emission-reducing operation. Traditional air conditioning energy-saving control methods sometimes calculate the difference between the real-time monitored ambient temperature and the set temperature, and then automatically switch the indoor fan on and off based on the difference. This unidirectional and single-load control method results in very low energy efficiency. Other methods use additional fresh air devices for selective control of the air conditioner. However, fresh air devices not only increase costs, but improper introduction of fresh air can easily increase the moisture load of the fresh air, leading to increased energy consumption.

[0060] Based on this, this application provides an air conditioning control method applicable to air conditioners in the aforementioned scenarios. The air conditioner includes a processor and a compressor, an indoor fan, and an outdoor fan connected to the processor. The processor acquires first temperature data related to the target device and the environment by connecting to an external temperature sensing device, and analyzes the first temperature data to obtain the initial operating parameters of the air conditioner; then, it controls the air conditioner to start operation according to the initial operating parameters, and acquires second temperature data related to the target device in real time; then, it couples and regulates the operating parameters of the air conditioner based on the second temperature data, controlling the cooling output of the air conditioner. This significantly reduces the ineffective energy consumption of the air conditioner and improves the energy-saving rate while ensuring the stable operation of the target device.

[0061] In one embodiment, such as Figure 1 As shown, an air conditioning control method is provided, including steps 102 to 106. Wherein:

[0062] Step 102: Obtain the first temperature data related to the target device and the environment, and analyze the first temperature data to obtain the initial operating parameters of the air conditioner.

[0063] The target device is the object to which the air conditioner's cooling output is applied. This could be communication equipment or electronic devices in a communication base station, or computers or servers in a computer room. The temperature related to the target device can be its surface temperature, the temperature of its core components, or a combined value of temperatures across the target device. This can be obtained by adding a temperature detection device to the target device, connecting to an existing temperature detection device, or by detecting it using an infrared temperature detection device. The environmental temperature can be the actual indoor temperature where the target device is located, the actual outdoor temperature where the target device is located, or the desired indoor temperature set by technicians. The actual indoor and outdoor temperatures can be obtained by installing temperature detection devices in both the indoor and outdoor environments where the target device is located.

[0064] Specifically, the initial temperature data can be understood as the temperature data related to the target device and the environment collected before the air conditioner is turned on. It can be used to analyze and obtain the initial operating parameters of the air conditioner, that is, the operating parameters corresponding to the cooling capacity demand of the target device in the initial state. The types of parameters included in the initial operating parameters are not unique, and may include the initial target frequency of the air conditioner compressor, as well as the initial target speed of the indoor and outdoor fans of the air conditioner, etc.

[0065] Step 104: Control the air conditioner to start running with the initial operating parameters and acquire the second temperature data related to the target device in real time.

[0066] Specifically, after obtaining the initial operating parameters, the various components of the air conditioner can be controlled to start operating according to the target values ​​corresponding to these initial operating parameters. Then, once the operating parameters of each component have stabilized to the initial operating parameters, the subsequent steps of acquiring temperature data related to the target device and adjusting the various components of the air conditioner proceed. It can be understood that the stabilization of the operating parameters of the air conditioner components to the initial operating parameters can be determined by waiting for the air conditioner to run for a preset stabilization period, or by detecting whether the air conditioner's operating parameters have reached the initial operating parameters. The preset stabilization period can be set according to the actual operating performance of the air conditioner; for example, in this embodiment, it can be set to 1-10 minutes. The second temperature data can be understood as the temperature data related to the target device collected after the air conditioner is turned on. This can be temperature data continuously collected from the moment the air conditioner is turned on until the preset stabilization period is reached, or it can be the temperature data corresponding to the moment the preset stabilization period is reached.

[0067] Step 106: Adjust the operating parameters of the air conditioner according to the second temperature data to control the cooling output of the air conditioner.

[0068] It is understood that the second temperature data includes temperature data related to the target device continuously collected from the moment the air conditioner is turned on until the preset stable time is reached. This data can be used to analyze the rate of temperature change of the target device. Furthermore, by combining the temperature of the target device at the time the preset stable time is reached, the required air conditioning control method for the environment in which the target device is located can be determined. The corresponding control method can then be used to adjust the operating parameters of the air conditioner so that the cooling output of the air conditioner meets the needs of the target device, ensuring that both the temperature and the rate of temperature change of the target device remain stable within the set range.

[0069] Specifically, when adjusting the operating parameters of an air conditioner using temperature data related to the target device, the correspondence between the target device's temperature data and the adjustment method can be pre-determined based on experimental data and stored in the air conditioner's main memory. When the adjustment method needs to be determined, the corresponding method can be found in the correspondence based on the real-time collected temperature data related to the target device. Alternatively, the adjustment method can be determined directly based on the real-time collected temperature data related to the target device, or it can be determined based on the temperature range to which the target device's temperature data belongs; there are no limitations, and the method can be determined based on the actual design of the correspondence.

[0070] Furthermore, the methods for adjusting the operating parameters of an air conditioner are not unique; they can include increasing cooling capacity, decreasing cooling capacity, or keeping cooling capacity constant. Clearly, when the adjustment method is to increase cooling capacity, the operating parameters will be changed to increase the cooling capacity output of the air conditioner; when the adjustment method is to decrease cooling capacity, the operating parameters will be changed to decrease the cooling capacity output of the air conditioner; and when the adjustment method is to keep cooling capacity constant, the operating parameters will remain unchanged. In addition, when the adjustment method is to increase or decrease cooling capacity, the operating parameters can also be controlled to change by different magnitudes to increase or decrease the cooling capacity output of the air conditioner.

[0071] It's understandable that the types of operating parameters used to regulate the cooling capacity output of an air conditioner are not unique. They can be operating parameters of various components affecting the cooling capacity output, such as the compressor's operating frequency, the speed of the indoor and outdoor fans, or combinations of these parameters. Furthermore, the roles and energy consumption of each component in air conditioner operation are not the same. For example, the indoor fan regulates the airflow, the outdoor fan regulates the airflow, and the compressor regulates the cooling capacity. The compressor's operating frequency has a greater impact on energy consumption than that of the indoor and outdoor fans. Therefore, when controlling the cooling capacity output of an air conditioner, priorities can be set for each operating parameter to achieve further energy savings. For example, when the control method is to increase cooling capacity, the indoor fan speed can be increased first, followed by increasing the compressor's operating frequency; when the control method is to decrease cooling capacity, the compressor's operating frequency can be decreased first, followed by reducing the indoor fan speed.

[0072] The aforementioned air conditioning control method first obtains the initial operating parameters of the air conditioner by analyzing the first temperature data related to the target device and the environment, and controls the air conditioner to start running with these initial operating parameters. Then, it directly uses the second temperature data related to the target device to couple and regulate the operating parameters of the air conditioner, so that the cooling output matches the cooling demand. This method can significantly reduce the ineffective energy consumption of the air conditioner and improve the energy saving rate while ensuring the stable operation of the communication equipment.

[0073] In one embodiment, the first temperature data includes the target device temperature T. e Indoor ambient temperature T i outdoor ambient temperature T o The initial operating parameters of the air conditioner include the initial target frequency f. t .like Figure 2 As shown, step 102, which involves analyzing the first temperature data to obtain the initial operating parameters of the air conditioner, includes steps 202 to 204. Wherein:

[0074] Step 202: Based on the target equipment temperature T e With the target equipment's maximum allowable temperature T t Perform difference calculation to obtain the temperature difference of the target equipment (|T) e -T t |). Among them, the maximum allowable temperature of the target equipment is the highest temperature at which the target equipment is allowed to operate. It is preset by technicians according to the requirements of the target equipment, and the value is not unique. For example, in this embodiment, the range can be set to 50-100℃.

[0075] Step 204: Based on the temperature difference (T) of the target equipment e -T t Indoor ambient temperature T i Outdoor ambient temperature T o The initial target frequency of the air conditioner is calculated using preset fitting coefficients.

[0076] The preset fitting coefficients can be obtained in advance by fitting the initial target frequency data from multiple test environments. Multiple sets of different indoor ambient temperatures T can be designed for the test environments. i Outdoor ambient temperature T o Target equipment temperature T e and the target equipment's maximum allowable temperature T t And the appropriate initial target frequency f to be used. t During the experiment, the indoor ambient temperature T i With outdoor ambient temperature T o The value can be selected between 10 and 60℃, and the target equipment temperature T e and the target equipment's maximum allowable temperature T t The value can be selected between 50 and 100℃. Then, the multiple temperature data from the above design are combined with the initial target frequency, and the preset fitting coefficients are obtained through the following multivariate linear fitting formula.

[0077] f t =aT o +bT i +c(T e -T t )+d

[0078] Where a, b, c, and d represent the outdoor ambient temperature T, respectively. o Indoor ambient temperature T i Temperature difference with target equipment (T) e -T t The preset fitting coefficients are not unique and can be obtained based on the actual experimental method. After obtaining the preset fitting coefficients, they can be combined with the currently detected temperature difference (T) of the target equipment. e -T t Indoor ambient temperature T i With outdoor ambient temperature T o The initial target frequency f required to turn on the air conditioner is calculated. t And control the air conditioning compressor to operate at the initial target frequency f until the preset stable operating time is reached. t Increase operating frequency.

[0079] In another embodiment, the initial operating parameters of the air conditioner also include the initial target fan speed of the indoor fan and the initial target fan speed of the outdoor fan. Specifically, the initial target fan speed of the indoor fan can be obtained according to the desired temperature set by the technician for the indoor ambient temperature. Furthermore, the indoor fan is controlled to operate at the speed corresponding to the initial target fan speed until the preset stable operating time is reached. The initial target fan speed can also be determined based on the detected indoor ambient temperature T. i Different initial target fan speeds are selected for different temperature ranges. Further control ensures that the outdoor fan operates at the speed corresponding to the initial target fan speed until the preset stable operating time is reached.

[0080] In one embodiment, the second temperature data includes the target device temperature T. e It is understandable that the target device temperature T e This refers to the temperature data of the target device obtained in real time after the air conditioner is turned on and running. For example... Figure 3 As shown, step 106, which involves adjusting the air conditioner's operating parameters based on the second temperature data, includes steps 302 to 304. Wherein:

[0081] Step 302: Based on the target equipment temperature T detected in real time after the air conditioner is turned on and running. e The analysis yielded the target equipment temperature change rate (dT) e / dt).

[0082] Specifically, after the air conditioner is turned on, the temperature T of multiple target devices can be detected at preset time intervals. e Then, the target equipment temperature T is obtained based on the collected continuous temperature data. e A function that changes with time. The rate of change of the target equipment temperature can be understood as the instantaneous rate of change of the target equipment temperature, which can be expressed as the target equipment temperature T.e It is obtained by differentiating the function as a function of time.

[0083] Furthermore, when it is necessary to obtain the control method of the air conditioner's operating parameters, such as when a preset stable duration is reached or when the control method changes, the target equipment temperature T can be obtained in real time after the air conditioner is turned on. e The analysis yielded the target equipment temperature change rate (dT) e / dt), and determine the corresponding control method. When determining the control method, the target equipment temperature T e With the rate of change of the target equipment temperature (dT) e / dt) can be used directly to determine the corresponding control method; or it can be used to determine the current target equipment temperature T after dividing the temperature range and the rate range. e Temperature range and rate of temperature change of the target equipment (dT) e The system determines the appropriate control method based on the temperature range and the rate range, which corresponds to the temperature range and the rate range. In this embodiment, the control method is determined by dividing the temperature range and the rate range.

[0084] Step 304: Adjust the operating parameters of the air conditioner according to the control method corresponding to the temperature zone to which the target equipment temperature belongs and the rate range to which the rate of change of the target equipment temperature belongs.

[0085] It is understandable that when the target device temperature T e When belonging to different temperature zones, or the rate of temperature change of the target equipment (dT) e When / dt) falls within different rate ranges, the cooling capacity requirement of the target equipment varies. Correspondingly, multiple temperature zones and rate ranges can be obtained based on the temperature value and temperature change rate value corresponding to the cooling capacity requirement of the target equipment, which can be used to determine the control method corresponding to the cooling capacity requirement of the target equipment.

[0086] Specifically, the control method represents the magnitude of the air conditioner's operating parameters that need to be adjusted according to the current cooling demand of the target equipment. This can be increasing a preset increase magnitude, decreasing a preset decrease magnitude, or maintaining the current operating state unchanged. The types of air conditioner operating parameters included under the control method are not unique and can be determined according to the actual control purpose. For example, the control method in this embodiment may include preset frequency increase magnitude and preset frequency decrease magnitude for adjusting the operating frequency of the air conditioner compressor, and preset speed increase magnitude and preset speed decrease magnitude for adjusting the speed of the air conditioner's internal fan.

[0087] In one embodiment, such as Figure 4As shown, step 304 involves adjusting the air conditioner's operating parameters according to the control method corresponding to the temperature zone to which the target equipment temperature belongs and the rate interval to which the target equipment temperature change rate belongs. This includes steps 402 to 406, wherein:

[0088] Step 402: When the control method corresponding to the temperature range of the target equipment and the rate range of the rate of change of the target equipment temperature is to increase the cooling capacity, adjust the operating parameters of the air conditioner to increase the cooling capacity output of the air conditioner.

[0089] Specifically, when the target equipment temperature T e The temperature change rate (dT) of the target equipment within the temperature zone e The combination of the rate ranges ( / dt) indicates that when the cooling demand of the target equipment is high, the operating parameters of the air conditioner can be adjusted to appropriately increase the cooling output to meet the higher cooling demand of the target equipment. The combination of the temperature zone and rate range indicating a high cooling demand of the target equipment is not unique. It can be that both the temperature value and the temperature rate change value corresponding to the temperature zone and rate range are high, or one of them is very high and the other is moderate. It can be designed according to actual needs, as long as the corresponding temperature range and rate range match the cooling demand of the target equipment.

[0090] Furthermore, when an air conditioner has multiple operating parameters, such as compressor operating frequency and indoor fan speed, the methods for adjusting these parameters to increase cooling output are not unique. They can be adjusted simultaneously on all parameters or adjusted according to priority. In one embodiment, such as... Figure 5 As shown, step 402, adjusting the operating parameters of the air conditioner to increase its cooling capacity output, includes steps 502 to 504, wherein:

[0091] Step 502: Control the internal fan speed to increase the speed according to the current control method.

[0092] Specifically, the current control method can be understood as the current target equipment temperature T being monitored. e The temperature change rate (dT) of the target equipment within the temperature zone e The control method corresponds to the rate range of / dt). When starting control, the indoor fan speed can be increased to increase the cooling output of the air conditioner, based on the preset speed increase range corresponding to the current control method.

[0093] Step 504: At the first preset time t i If the temperature zone of the target equipment and the rate range of the rate of change of the target equipment temperature remain unchanged, the operating frequency of the compressor is increased according to the current control method.

[0094] It is understandable that the first preset time t i Used to wait for the target equipment temperature T e The temperature change rate (dT) of the target equipment within the temperature zone e The rate range of / dt) will affect whether the way the cooling output of the air conditioner increases due to increasing the speed of the internal fan will change. Therefore, the specific value of the first preset time is not fixed and can be set according to actual needs. In this embodiment, the value can be taken within 0 to 10 minutes.

[0095] Specifically, at the first preset time t i Then, based on the real-time detected target equipment temperature T e Determine the target equipment temperature T e The temperature change rate (dT) of the target equipment within the temperature zone e The rate range of / dt). If either the temperature zone or the rate range changes, since the cooling output is being increased, the changed temperature zone or rate range obviously indicates a decrease in temperature or a slowdown in the rate of temperature change. Correspondingly, this means that increasing the internal fan speed to increase the cooling output of the air conditioner is sufficient to meet the cooling demand of the current target equipment. There is no need to continue increasing the compressor frequency according to the current control method. We can return to step 304 to redetermine the control method and adjust the air conditioner's operating parameters according to the new control method, thus achieving the goal of saving energy.

[0096] If neither the temperature zone nor the speed range changes, it means that increasing the internal fan speed to increase the cooling output of the air conditioner is not currently meeting the cooling demand of the target equipment. Therefore, based on the preset frequency increase in the current control method, the compressor is controlled to increase its operating frequency to increase the cooling output of the air conditioner.

[0097] Step 404: When the control mode corresponding to the temperature range of the target equipment and the rate range of the target equipment temperature change rate is cooling capacity reduction, adjust the operating parameters of the air conditioner to reduce the cooling capacity output of the air conditioner.

[0098] Specifically, when the target equipment temperature T e The temperature change rate (dT) of the target equipment within the temperature zone e The combination of the rate ranges ( / dt) indicates that when the cooling demand of the target equipment is low, the operating parameters of the air conditioner can be adjusted to appropriately reduce the cooling output, as long as the low cooling demand of the target equipment is met. The combination of the temperature zone and rate range indicating a low cooling demand of the target equipment is not unique. It can be that both the temperature value and the temperature rate change value corresponding to the temperature zone and rate range are low, or one of them is very low and the other is moderate. It can be designed according to actual needs, as long as the corresponding temperature range and rate range match the cooling demand of the target equipment.

[0099] Furthermore, adjusting the air conditioner's operating parameters to reduce its cooling output can also be done by simultaneously adjusting all operating parameters or by adjusting each operating parameter according to priority. In one embodiment, such as Figure 6 As shown, step 404 involves adjusting the operating parameters of the air conditioner to reduce its cooling output, including steps 602 to 604, wherein:

[0100] Step 602: Control the compressor operating frequency to reduce the operating frequency according to the current control method; specifically, since the compressor frequency has a relatively large impact on the energy consumption of the air conditioner, in the control method of reducing the cooling output, the compressor frequency can be reduced according to the preset frequency reduction range corresponding to the current control method to reduce the cooling output of the air conditioner, thereby achieving the purpose of reducing energy consumption.

[0101] Step 604: At the first preset time t i Subsequently, if the temperature zone to which the target equipment temperature belongs and the rate range to which the rate of change of the target equipment temperature belongs remain unchanged, the speed of the internal fan will be increased according to the current control method.

[0102] Specifically, the first preset time t i The definition is similar to that in step 504, and will not be repeated. Similarly, at the first preset time t i Then, based on the real-time detected target equipment temperature T e Determine the target equipment temperature T e The temperature change rate (dT) of the target equipment within the temperature zone e The rate range of / dt). If either the temperature zone or the rate range changes, since the cooling output is being reduced, the changed temperature zone or rate range obviously indicates an increase in temperature or a faster rate of temperature change. Correspondingly, this means that reducing the compressor frequency to decrease the cooling output of the air conditioner does not currently meet the cooling demand of the target equipment. Therefore, it is not necessary to continue reducing the indoor fan speed according to the current control method. It is necessary to return to step 304 to redetermine the control method and adjust the air conditioner's operating parameters according to the new control method to meet the cooling demand of the target equipment.

[0103] If neither the temperature zone nor the speed range changes, it means that reducing the compressor frequency to decrease the cooling output of the air conditioner can still meet the cooling demand of the target device. Therefore, based on the preset speed reduction range in the current control method, the indoor fan speed can be further reduced to decrease the cooling output of the air conditioner.

[0104] Step 406: When the control mode corresponding to the temperature zone to which the target equipment temperature belongs and the rate interval to which the rate of change of the target equipment temperature belongs is constant, the air conditioner continues to operate with the current operating parameters.

[0105] Specifically, when the target equipment temperature T e The temperature change rate (dT) of the target equipment within the temperature zone e The combination of the temperature zone and rate range ( / dt) indicates that when the cooling demand of the target equipment is moderate, the operating parameters of the air conditioner can be adjusted to maintain the current cooling output at a constant level, thus stabilizing the cooling demand of the target equipment. The combination of the temperature zone and rate range that indicates moderate cooling demand is not unique. It can be that both the temperature value and the temperature rate change value of the temperature zone and rate range are moderate, or one of them is slightly higher and the other is very low. It can be designed according to actual needs, as long as the corresponding temperature range and rate range match the cooling demand of the target equipment.

[0106] It is understood that during the control process in step 304, the operating parameters of the air conditioner are controlled to cycle between various control modes in accordance with the method described in the above embodiment. This is based on the real-time detected target equipment temperature T. e Determine the target equipment temperature T e The temperature change rate (dT) of the target equipment within the temperature zone e If any change occurs within the rate range of / dt), the control mode can be redefined and the operating parameters of the air conditioner can be adjusted according to the new control mode.

[0107] Furthermore, when determining the control method based on the temperature zone of the target equipment and the rate interval of the rate of temperature change, the number of temperature zones and rate intervals is not fixed. It can be determined according to the actual number of control methods required. For example, three temperature zones can be obtained based on two temperature values, and three rate intervals can be obtained based on two rate change values. These combinations then correspond to the determined control methods. Correspondingly, the control methods corresponding to various combinations of temperature zones and rate intervals can be the same; for example, they can all correspond to a control method that increases cooling capacity, but with different preset increase or decrease amplitudes.

[0108] The following table illustrates the division of temperature and speed zones, along with their corresponding control methods, to explain the control process of air conditioning operation.

[0109]

[0110]

[0111] In this embodiment, the target device temperature change rate (dT) is determined by the first rate threshold v1 and the first rate threshold v2.e The rate is divided into two intervals, where / dt) represents the rate of change of the target equipment temperature. e When / dt) is greater than or equal to the first rate threshold v1, the target device temperature change rate (dT) e The rate interval to which / dt belongs is the first rate interval; the target equipment temperature change rate (dT) is within the first rate interval. e When the rate of change of the target device temperature (dT) is less than the first rate threshold v1 and greater than or equal to the first rate threshold v2, e The rate interval to which / dt) belongs is the second rate interval; the target equipment temperature change rate (dT) e When / dt) is less than the first rate threshold v2, the target device temperature change rate (dT) e The rate interval to which / dt) belongs is the third rate interval. Among them, the values ​​of the first rate threshold v1 and the first rate threshold v2 are not limited, and the value range can be 0 to 0.5℃ / min.

[0112] This embodiment also uses a first temperature amplitude threshold e, a second temperature amplitude threshold g, and the target device's maximum allowable temperature T. t Determine the first temperature threshold (T) t -e) and the second temperature threshold (T) t -g), and then based on the first temperature threshold (T) t -e) and the second temperature threshold (T) t -g) The target equipment temperature T e It is divided into two temperature ranges. Among them, the target equipment temperature T... e Greater than or equal to the first temperature threshold (T) t When -e), the target equipment temperature T e The temperature range it belongs to is the first temperature zone; at the target equipment temperature T e Less than the first temperature threshold (T) t -e), greater than or equal to the second temperature threshold (T) t When -g), the target equipment temperature T e The temperature range it belongs to is the second temperature zone; at the target equipment temperature T e Less than the second temperature threshold (T) t When -g), the target equipment temperature T e The temperature range it belongs to is the third temperature zone. Among them, the values ​​of the first temperature amplitude threshold e and the second temperature amplitude threshold g are not limited. The value range of the first temperature amplitude threshold e can be -10 to 0℃, and the value range of the second temperature amplitude threshold g can be 0 to 10℃.

[0113] As shown in the table, when the target equipment temperature T e The temperature zone in question is the first temperature zone, and the target equipment temperature change rate (dT)e When the rate range of / dt) belongs to the first rate range, it indicates that the target equipment temperature is very high and the temperature change rate is also very fast. The corresponding control method is to increase the speed of the internal fan by Δv1 and increase the target frequency of the compressor by Δf1. When the target equipment temperature T e The temperature zone in question is the first temperature zone, and the target equipment temperature change rate (dT) e When the rate range of / dt) belongs to the second rate range, it indicates that the target equipment temperature is very high and the temperature change rate is moderate. The corresponding control method is to increase the internal fan speed by an increase of Δv2 and the compressor operating target frequency by an increase of Δf2. When the target equipment temperature T e The temperature range is the second temperature range, and the target equipment temperature change rate (dT) e When the rate range of / dt) is the first rate range, it indicates that the target equipment temperature is moderate and the temperature change rate is very high. The corresponding control method is to increase the internal fan speed by an increase of Δv3 and the compressor operating target frequency by an increase of Δf3. Where Δv1≥Δv2, Δv1≥Δv3, Δf1≥Δf2, and Δf1≥Δf3.

[0114] When the target equipment temperature T e The temperature zone in question is the first temperature zone, and the target equipment temperature change rate (dT) e The rate range to which / dt belongs is the third rate range, and the target equipment temperature T e The temperature range is the second temperature range, and the target equipment temperature change rate (dT) e The rate range to which / dt belongs is the second rate range, and the target equipment temperature T e The temperature zone it belongs to is the third temperature zone, and the target equipment temperature change rate (dT) e When the rate range of / dt) is the first rate range, it indicates that the temperature of the target equipment and the rate of temperature change are relatively stable, the cooling demand is moderate, and the corresponding control method is to keep the current operating parameters of the air conditioner unchanged.

[0115] When the target equipment temperature T e The temperature range is the second temperature range, and the target equipment temperature change rate (dT) e When the rate range of / dt) belongs to the third rate range, it indicates that the target equipment temperature is moderate and the temperature change rate is very low. The corresponding control method is to reduce the internal fan speed by a decrease of Δv4 and the compressor operating target frequency by a decrease of Δf4. When the target equipment temperature T e The temperature zone it belongs to is the third temperature zone, and the target equipment temperature change rate (dT) eWhen the rate range of / dt) belongs to the second rate range, it indicates that the target equipment temperature is very low and the temperature change rate is moderate. The corresponding control method is to reduce the internal fan speed by Δv5 and the compressor operating target frequency by Δf5. When the target equipment temperature T e The temperature zone it belongs to is the third temperature zone, and the target equipment temperature change rate (dT) e When the rate range of / dt) is the third rate range, it indicates that the target equipment temperature is very low and the rate of temperature change is also very low. The corresponding control method is to reduce the internal fan speed by a decrease of Δv6, and reduce the compressor operating target frequency by a decrease of Δf6. Where Δv6 ≥ Δv4, Δv6 ≥ Δv5, Δf6 ≥ Δf4, and Δf6 ≥ Δf5. The values ​​of Δv1, Δv2, Δv3, Δv4, Δv5, and Δv6 can range from 0 to 100 rpm, and the values ​​of Δf1, Δf2, Δf3, Δf4, Δf5, and Δf6 can range from 0 to 10 Hz.

[0116] In one embodiment, such as Figure 7 and Figure 8 As shown, after the compressor operating frequency is increased according to the current control method in step 504, the method further includes steps 702 to 706, wherein:

[0117] Step 702: Real-time monitoring of the air conditioner's processor temperature T m The temperature of the air conditioner's processor can be obtained by placing a temperature detection device near the air conditioner processor.

[0118] Step 704: At processor temperature T m When the temperature is greater than or equal to the first preset temperature T1, the compressor operating frequency is controlled according to the current regulation method at the first preset frequency increase rate Δv. s Increase the operating frequency. The first preset temperature T1 represents the temperature threshold of excessive load during the frequency ramp-up process; its value can be set according to actual needs, for example, within the range of 60–100℃. The first preset frequency ramp-up rate Δv s The value is not unique; for example, in this embodiment, it is selected within the range of 1 to 5 Hz / s.

[0119] Step 706: At processor temperature T m When the temperature is below the first preset temperature T1, the compressor operating frequency is controlled according to the current regulation method at the second preset frequency increase rate Δv. f Increase the operating frequency. Specifically, the second preset frequency ramp-up rate Δv f The value is not unique; for example, in this embodiment, it is selected within the range of 1 to 5 Hz / s. However, it can be understood that the first preset upsampling rate Δv s It must be less than the second preset upsampling rate Δvf .

[0120] In this embodiment, it can be understood that during the process of increasing the operating frequency of the compressor according to the current control method, if it is determined that the load of the air conditioner is too large based on the processor temperature and the first preset temperature T1, the frequency increase rate needs to be reduced to ensure system reliability.

[0121] In one embodiment, such as Figure 9 and Figure 10 As shown, after the air conditioner is turned on with initial operating parameters in step 104, the method further includes steps 802 to 806, wherein: Step 802: Real-time detection of the air conditioner's processor temperature T m The processor temperature data acquired in this step can be obtained using the same temperature detection device as in step 702. Step 804: At processor temperature T... m When the temperature is lower than the second preset temperature T2, the step of acquiring the second temperature data related to the target device in real time is executed.

[0122] It is understandable that the second preset temperature T2 represents the threshold for excessively high processor temperature during air conditioner operation. The value can be set according to actual needs, for example, within the range of 60–100℃. Processor temperature T m If the temperature is less than the second preset temperature T2, it means that the processor temperature T m If the temperature is within the normal range, the process can continue with the step of acquiring the second temperature data related to the target device in real time. Then, the operating parameters of the air conditioner can be adjusted.

[0123] Step 806: At processor temperature T m When the temperature is greater than or equal to the second preset temperature T2, the compressor operating frequency and the outdoor fan speed of the air conditioner are reduced until the processor temperature T2 is reached. m The temperature is less than the third preset temperature T3 and the duration is greater than the preset duration t. k Return to step 102; wherein the third preset temperature T3 is less than the second preset temperature T2.

[0124] It is understandable that at processor temperature T m When the temperature is too high, the power consumption of the compressor and the outdoor fan can be reduced by controlling the compressor operating frequency and the outdoor fan speed, thereby effectively reducing the temperature of the processor module.

[0125] Specifically, if the temperature T of the detection controller module is... m If the temperature is greater than or equal to the second preset temperature T2, the compressor operating frequency of the air conditioner will decrease by Δf7, and the outdoor fan speed will decrease by Δv7; if continuous operation has reached the preset time t... j Then continue with processor temperature T. mThe judgment; if the processor temperature T m If the temperature is still greater than or equal to the second preset temperature T2, then the frequency reduction and fan speed reduction process will continue: the compressor operating frequency of the air conditioner will be reduced by Δf7, and the outdoor fan speed will be reduced by Δv7, until the processor temperature T... m The temperature is less than the third preset temperature T3 and the duration is greater than the preset duration t. k At processor temperature T m The temperature is less than the third preset temperature T3 and the duration is greater than the preset duration t. k If the initial operating parameters are not found in step 102, the air conditioner is controlled to operate according to the initial operating parameters. Second temperature data related to the target device is detected, and the operating parameters of the air conditioner are adjusted based on the second operating data. The preset time t... j With preset duration t k All of these can be selected according to actual needs. For example, the value range can be 0–30 min, the value range of Δf7 can be 2–10 Hz, and the value range of Δv7 can be 50–150 rpm. The values ​​of the second preset temperature T2 and the third preset temperature T3 can be 60–80℃.

Specifically, after entering the control mode of reducing cooling capacity control 1, the compressor's operating target frequency is first controlled to decrease by a frequency decrease of Δf4. During the process of decreasing the compressor's operating frequency, a first preset time t is continuously applied. i Inside, detect the temperature T of the target equipment. e If the temperature zone and the equipment temperature rise rate have changed, then switch to the corresponding temperature and temperature rise rate range control mode for control; otherwise, control the internal fan speed to decrease according to the speed decrease range of △v4.
